General Modified Friedmann Equations in Rainbow Flat Universe, by Thermodynamics

open access: yes, 2019
We investigate the derivation of Friedmann equations in Rainbow gravity following Jacobson thermodynamic approach. We do not restrict the rainbow functions to be constant as is customarily used, and show that the first law of thermodynamics with a ...

Domain Wall Rebounds Driven by Competing Entropic and Spin‐Transfer Torques in Cylindrical Nanowires

open access: yesAdvanced Functional Materials, EarlyView.
Domain‐wall motion in cylindrical magnetic nanowires driven by nanosecond current pulses. Low current densities efficiently displace domain walls, whereas higher currents cause rebound at the wire ends. The effect results from the interplay between spin‐transfer torque and thermally induced processes, highlighting the role of thermal gradients in ...

Proportionality and Margin of Appreciation in the Whaling Case. Reconciling Antithetical Doctrines? [PDF]

open access: yes, 2016
In its decision on the Whaling in the Antarctic case, the International Court of Justice used a sophisticated methodology for assessing the legality of a whaling program allegedly designed to pursue purposes of scientific research.

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

The ORSA requirement : insurance practitioners’ concerns [PDF]

open access: yes, 2017
ORSA requires every insurance company to demonstrate that it has an effective Risk Management program, with scenario analysis, stress testing and capital solvency models in place that can help it withstand normal and extreme risk events. Each ORSA report

Photon Avalanching Nanoparticles: The Next Generation of Upconverting Nanomaterials?

open access: yesAdvanced Functional Materials, EarlyView.
This Perspective outlines the mechanistic foundations that enable photon‐avalanche (PA) behavior in lanthanide nanomaterials and contrasts them with emerging application spaces and forward‐looking design strategies. By bridging threshold engineering, energy‐transfer dynamics, and materials engineering, we provide a coherent roadmap for advancing the ...

Prevention, Proxies, and the Limits of Self-Defence: International Law and the Security Dilemma in the Israel–Iran Rivalry [PDF]

open access: yesThe Review of International Affairs
This article examines how power, discourse, and law interact to drive escalation in the Israel–Iran rivalry. It asks under what conditions a claim of self-defence crosses into unlawful prevention.

Dynamics of Magnetized Bulk Viscous Strings in Brans-Dicke Gravity

open access: yes, 2012
We explore locally rotationally symmetric Bianchi I universe in Brans-Dicke gravity with self-interacting potential by using charged viscous cosmological string fluid.
